The Russellville School District increased security at the middle school Monday morning following threats made on a social media site over the weekend.

"We have beefed up security," Assistant Superintendent Alene Bynum said. "We have local and county officers here [at the middle school]. We have additional staff on hand and people from Central Office here."

The district was told by a parent that a student allegedly threatened a small group of students on ask.fm, a social media site.

"The parents of these students have been notified," Ashley Snellenberger, RSD communications coordinator, said. "RSD takes the safety and security of our students seriously."

Russellville Middle School continued with normal school hours Monday, although many students got picked up early by concerned parents as news of the alleged threats spread.

It is unknown at this time if the student who allegedly made the threats has been suspended. Snellenberger said the district can't release information about students.

The Russellville Police Department is investigating the incident.

Ask.fm is asocial media website set up in a question and answer format that offers anonymity. The content on ask.fm is unmonitored and the site has been associated with numerous instances of cyberbullying since 2012.

The site, which was created in 2010, has more than 80 million registered users now.
